Vintage Group Photo of Teenagers (1920s)

Here is the first β€œFound Photo” post of 2022. I picked this up at a local antique store a few days ago. The image is incredibly crisp and shows a group of what looks to be teenagers from the 1920s. I could be wrong on the date. What do you think?

There is man on the right side who appears to be older. I am guessing he is a teacher and that this is a school photo.
